Insert two short steel stiffeners into one long steel stiffener to
create full length piece. Repeat so you have four full length beams.
Insert the end of the vinyl beam (without a hole), into the joiner.
Install the joiners so that the side with the four holes are facing up.
Push firmly until the extrusion bottoms out inside the joiner.
Please Note:
Ensure to orientate the main beams correctly so the pre-drilled
holes for future installation of rafter brackets is correct.
Insert one assembled steel stiffener (with steel block facing up),
into the lower pocket of the vinyl beam past the joiner. Push
until steel block hits the internal ribbing.
Slide the other vinyl beam over the steel insert and into the joiner.
Screw the joiner to vinyl beams and steel insert using 1 1/2”
screws. The bottom and top holes will need to be pre-drilled
(use drill bit provided).
Install the rafter brackets to the main beams using 5/8”
screws. Follow the pre-drilled holes to identify locations.
